My V20 already had the scuppers out the sides but I did move the deck drain from "in the deck" to "on the bulkhead". This was because there was always a little wtaer that would not go down the drain due to the lip of the fitting.
If you move the scuppers, you have to get it right. look at the height above the waterline and where your deck drains are. They also have to be astern of the deck drain.
Think about how the hose will bend.
You are not going to have any wood anymore, so not sure what benefit you get moving from transom.
